I've seen that. It's not oil or grease at all, it's the "potting" plastic from the voltage regulator. It means that the alternator has been pretty hot at some point. Mine was still working when I replaced it, and it looked like that for a looong time - several years. If you take the alternator apart you'll find that plastic sealing the voltage regulator chip has melted and you can see the chip module itself. So - probably not an emergency, but put it on your to-do list.
